Unless you want to try very minimal system you probably want shadow
passwords.

You may have hit a bug. I noticed a problem with disabling shadow
passwords some time back and I don't know if anyone has fixed it, as
(ahem) I haven't gotten around to reporting it yet...
I recall (maybe wrongly) figuring out that when shadow passwords were
not enabled, installer still saved root password into shadow before
disabling it, or something on those lines.
I could fix my installation at the time by going into single user mode
and changing root password, after which it worked correctly.
